SPECIFICATION forming part of Letters Patent No. 776,126, dated November 29, 1904. Application tiled December 28, 1903. Serial No. 186,787. (No model.)

To all whom, t weary concern:

Re it known that LCL/rus A. EDLUND, a resident of Providence, in the county of Providence and State of Rhode Island, have invented certain new and useful Improvements in Vises;

and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the numerals of reference marked thereon, which T'orrn a part of this specilication. Y

This invention pertains to vises, the object of which being to construct an improved form of universally-jointed or swivel vises particu- I5 larly designed for use in the machine-shop in the construction or iinishing ot' the liner class of work.

A further object of the invention is to so construct the vise that each of the jointed 2O parts will have a bearing-surface of considerable extent,with means for securing said joints to prevent the work from vibrating or chattering' while being operated upon in the visejaws.

With these and other objects in view the invention consists of certain novel features of construction, as will be hereinafter more fully described, and particularly pointed out in the appended claims.

In the drawings, Figure 1 is a side elevation of my device, partly in section. Fig. 2 is a sectional end elevation on line 2 2 of Fig. 1 looking in the direction of the arrows. Fig. 3 is a sectional plan view on line 3 3 of Fig. 1 looking in the direction of the arrows.

Fig. 1 is a plan View of the pivoted 'frame with the vise portion removed. Fig. 5V is a top plan view of the vise portion.

Referring to the drawings, 1 is the base portion, by which the vise is secured in any desired position. 1t is scored or channeled out at 2 on a radius from the center of the pivoting-bolt 7. This base portion is also counterbored at 11, leaving the two side ears 5 5 to receive the trarne portion 6, which tits closely between and is pivoted to said ears on the base portion by the pivot-bolt 7.

At 8 is a rib made to fit closely in the circular recess 2 of the base for the purpose of giving a greatly-increased bearing-surface and prevent chattering when the work in the vise is being operated upon. The set-screws 9 9 are for the purpose of being set up on each side oi the rib 8, locking the frame in the desired position, said screws themselves being locked from moving by the checlcnuts 10 10. This trame 6 may be swung down at an angle oi ninety degrees about the axis oi the horizontal pivot-bolt 7 'from the position shown in the drawings, bringing its face 11 down 60 against the rest-block 12, or it may be held at any angle between the two points and securely locked there by the set-screws described above.

The circular edge of the base portion is graduated at 13 to facilitate the accurate setting of the frame at the desired angle. The upper face of this frame 6 is counterbored on a bevel at 111 to receive a corresponding' circular beveled projection 15 on the under side 70 of the vise portion 16. This vise portion is held to be rotated horizontally about the axis of a vertical center bolt 17, which is arranged to be set up and bind the vise in place by the nut 18, which nut is set into a recess 19 in the 75 frame. This nut is threaded onto the end of said bolt and is made in the form or a wormgear, having teeth cut on its outer edge, which teeth are engaged by a screw-threaded shaft 20, which serves as tht` worin and extends 30 through the Frame 6 from side to side, having a lnurled handle 2l on one side, by which it is turned, and a nut and check-nut on its 0pposite end at 22.

At 29 is a graduated section on the circular 85 edge oi the frame portion, which graduation is for convenience in setting the vise portion at the desired angle as it is swung' horizontally about the axis olE the center bolt 17.

At 23 is the adjustable jaw portion of the 90 vice. This jaw has a long tapped hole 24 made through its center portion at 23. This hole docs not form a complete circle, the bottom portion of it being open, as shown at I.) in Fig. 2. A very short screw 25, which engages said tapped hole, is fixed to the end of a short shaft 26, which latter is squared lEor a wrench or handle at its outer end and is held in position in the bearing 27 by the check-nuts 28. 'Ihis bearing 27 is preferably made integral with the bed of the vise, being semicircular in form and smaller in diameter than that ot' the threaded hole in the jaw, thus allowing' said jaw to be drawn back completely over this bearing, giving the jaws otl the vise an unusually wide opening for one ot' its size.

. The ordinary method of reciprocating this jaw is by a long rotatable screw which is threaded through a short nut,which nut is tixed to the under side of the movable vise-jaw. By this construction the force is applied far below the line ot' resistance.

My method ot constructing the vise is much more practical than that above described, iirst, because the power is applied in a direct line of the resistance; second, because the jaws are capable of being opened to their fullest extent, wider than that of any other construction for a given size; third, the screw and threaded portion of the adjustable parts are entirely covered over, thus etfectually avoiding the annoyance ot' chips and dirt falling therein to prevent the free movement ot' the jaws.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, isg

1. In a device of the character described, in combination, a base portion, a frame portion to rotate vertically in said base, a bearing or steadying rib on said frame extending into said base, means for adjusting and securing said frame in the desired position as it is swung around said pivot, a vise pivoted to swing horizontally on said trame, means including a worm-gear which serves as a nut for bindingsaid vise to said frame.
